How Bigger Bullpens Are Constraining Offense

Nathan Ray Seebeck-USA TODAY Sports

This is a story about persistence. I thought I had an interesting way of looking at the marked decline in scoring this year so far; as it turns out, I was wrong. A further investigation, however, revealed that another possible culprit was right around the corner. Does it explain the entire decline in offense? Most certainly not. But I’m interested nonetheless, and I hope you will be too.

If you’ve followed baseball in the past five years, you’re probably used to asking questions about league-wide offense early in the season. Major League Baseball has done itself no favors here; the composition of the baseball keeps changing, and home run rates fluctuate wildly as a result. The same is true this year: despite the adoption of a universal DH, offense is down across the board.

The usual suspects are certainly part of the problem. Pitchers keep throwing harder. Putting a humidor in every stadium affects home run rates in unpredictable ways and might suppress home run rates early in the season. The league used two different baseballs last year, and drag coefficient is up this year. Starters are going fewer and fewer innings, giving batters fewer looks at them a third time through the order.

I think that all of those things have something to do with bad offense. But I thought of another potential cause, one I could investigate without learning fluid dynamics. One of the side bargains between the league and the MLBPA after this offseason’s lockout was for expanded rosters early in the season. Teams are allowed to roster 28 players throughout the month of April. On May 30, that number will revert to the standard 26 — this deadline was recently pushed back from May 1. In addition, teams can carry any number of pitchers on their roster until May 1. After that, they’ll be limited to 14, and 13 after May 29.

Modern Baseball, Fast and Slow, For Better and (Sometimes) Worse

Nathan Ray Seebeck-USA TODAY Sports

If you were looking for fast-paced, high-stakes baseball action, the tenth inning of Saturday’s Rays-Red Sox clash had everything you could ask for. Scoring? Five runs crossed the plate. Drama? There was a walk-off hit. Balls in play? The Red Sox hit a triple, and the Rays scored a run by combining a balk and a throwing error. Like home runs? It had one of them too.

If you were looking for grind-it-out, low-scoring, perfectly pitched baseball, the other nine innings would have been more your speed. Boston and Tampa Bay combined for two hits and seventeen strikeouts. They used ten pitchers. Runs? Only four runners so much as reached second base.

Which one is modern baseball? They both are. If you wish baseball had more balls in play, with more bunts and steals and plays at the plate, I can’t blame you. If you wish it had more dominant starting pitchers and more seven-inning starts that end with a mound conference and a manager talked into leaving his ace out there for just one more batter, I can’t blame you. But the game being played today is just as captivating, the performances just as impressive. They just come in different shapes and sizes.

Two Managerial Decisions and Another Questionable Intentional Walk

Rick Osentoski-USA TODAY Sports

As you may already know, I’m something of an intentional walk connoisseur here at FanGraphs. When questionable ones occur, particularly in the playoffs, I like to delve into the specifics to figure out which ones are good decisions, which ones are close calls, and which ones are just plain silly.

Earlier this week, I wrote about Joe Maddon’s bases-loaded intentional walk, which was about as far on the silly end of the spectrum as you can get. Today, I’m going to cover the other notable intentional walk of the week: the Yankees giving Miguel Cabrera a free pass on Thursday. Then, as a bonus, I want to talk about Cardinals manager Oli Marmol and a clever thing he did that might escape notice if you aren’t watching closely.

Shohei Ohtani Is Getting Better

Troy Taormina-USA TODAY Sports

Shohei Ohtani was up to some Tungsten Arm O’Doyle antics last night. He batted twice before throwing his first pitch of the game, something no one had accomplished in the recorded history of baseball. He bunted for a hit in the sixth inning while throwing a perfect game, almost assuredly the first time any pitcher has done that. That’s par for the course for Ohtani.

If you spend too long thinking about his record-breaking unicorn status, though, you might miss this fact: Ohtani has never looked better on the mound. Last year, he was a hitter first and a pitcher second; his 3.18 ERA over 130 innings was certainly impressive, but it wasn’t the equal of his .257/.372/.592 batting line and 46 home runs. This year, he’s off to a slower start with the bat — not a poor start, to be sure, but not the equal of last season. On the mound, though, he’s looking better and better. If 2021 was the year of Ohtani (hitter-first), 2022 might be the year of Ohtani (pitcher-first), with last night’s brush with perfection signaling his arrival. Read the rest of this entry »


Kyle Freeland Signs Up for Five More Years (Ish) in Denver

Ron Chenoy-USA TODAY Sports

Kyle Freeland and the Rockies were set for a tense arbitration session. He had asked for $7.8 million; they countered with $6.425 million. That was the fourth-largest gap between team and player across all of baseball. But good news for people who don’t like contentious negotiations: That’s all in the past, because both parties agreed to a five-year extension that supersedes the arbitration dispute and should keep Freeland in Denver for the foreseeable future.

The deal, which buys out three seasons of free agency, has all kinds of bells and whistles. At its core, it’s a five-year, $64.5 million contract, which will pay him $7 million, $10.5 million, $15 million, $16 million, and $16 million for the next five years. If Freeland pitches 170 innings in ‘26, he’ll trigger a player option for the 2027 season, which would pay him $17 million. But wait, there’s more! If Freeland finishes in the top five in Cy Young voting in either 2022 or ’23, he can opt out after ’24; if he’s showing Cy Young form, he’d presumably do so.

This deal is somehow the largest contract the Rockies have given to a pitcher since Darryl Kile and simultaneously not one of the top five deals signed by starting pitchers since the end of last season. As befits a deal that is simultaneously large and small, I’m of two minds about it. Read the rest of this entry »

Bonus Intentional Walk Math: The Big Bang Theory

Yesterday, I wrote about the intentional walk heard ‘round the world. It was mostly reflex, really. When someone issues a strange intentional walk, I can’t help but dig through the numbers. But this one, I was quite sure from the start, was bad. The math was just a way of rubbernecking, staring at a baseball accident from across the highway and saying “Wow, I wonder how that happened?”

But in doing so, I didn’t engage Joe Maddon on his weird, hipster-glass-wearing turf. Maddon didn’t say he was trying to minimize run expectancy (though he should have been). He didn’t say he was trying to maximize his team’s chances of winning the game (though he should have been). He said he was trying to “avoid the big blow,” or prevent a big inning in other words.

Bad news, Joe! Using the same simulation I used to estimate run and win expectations, I can work out the chances of a “big blow” for some arbitrary definition of big. Take my initial simulation. I estimated that the Rangers stood to score roughly 1.75 more runs in the inning when Corey Seager came to the plate, before any intentional walk shenanigans. We aren’t limited to looking at that in terms of average runs, though. It can also be expressed as some likelihood of scoring zero runs, one run, two runs, etc:

Run Matrix, Pre-Seager Walk
Runs Likelihood
0 24.7%
1 30.2%
2 16.5%
3 11.3%
4 10.3%
5 4.4%
6+ 2.6%

Don’t Intentionally Walk Anyone With the Bases Loaded

You had to know this one was coming. The moment needs no introduction; let’s just start with a clip:

Intentional walk. Bases loaded. Mike Trout staring homeward in disbelief:

Was this a solid baseball decision by the numbers? No. No, it was not. I don’t really have to do the math to tell you that. But doing the math is what we do here at FanGraphs, so just to be certain, and also just for the sake of doing it, I ran through the details. You don’t have to read this article to learn whether it was a good choice or not. I’m telling you that part right up front – it wasn’t. Read the rest of this entry »


Curb Your Kwanthusiasm (But Just a Little Bit)

© Jay Biggerstaff-USA TODAY Sports

Welcome to KwanGraphs, your source for everything… wait, no, that’s not right. Welcome to FanKwan, your … no, still not it. This part is definitely true, though: today I’m here to talk about Steven Kwan, the Guardians phenom who swung for our hearts and didn’t miss. He was our No. 57 prospect heading into the season, and ZiPS concurred, calling him its No. 62 prospect. He’s been better than that so far — a top 10 hitter in baseball, more or less. Can he keep it going? Will he bat .330 with more walks than strikeouts? I crunched data and watched film to come up with some educated speculation.

Let’s start with the great news: Kwan’s phenomenal bat control is as real as it gets. He’s swung and missed either one or two times (and hey, good news for pedants everywhere, I’ve even thrown in a special postscript at the end of this post so everyone can whinge about foul tips in the comments) in his major league career so far, which is obviously great. Even better, this isn’t something new. In 2021, he was the best contact hitter in the minors, bar none.

Over 1,388 pitches I captured, Kwan swung 551 times. He swung and missed 39 times, and had another seven foul tips. That’s a swinging strike rate of either 2.8% or 3.3% depending on your definition, both of which are otherworldly. The contact rate is no joke, either: he made contact on more than 90% of his swings, which led the high minors and would have placed him in a dead heat with David Fletcher for best in the big leagues.
